This invention under consideration consists of an apparatus with which within a short time a large number of broind of silver postcards can he produced in Aany piece desired. The apparatus consists chiefly of .fi Well- 2 known copying arrangement, and also ot' e well-known transport system, by means of -iti eh the peper is carried on rollers through the various receptacles ifoi liquid, and these te errsnjfmnenrs ere united in one wholen the union of the The invention consists in Well-known development arrangement with the Copying apparatus known in :ill its chieil points through the ernian patent document te 265:20, sincenot` onlvltlie pressure of the copyingpaper on the negative the opening and @losingl ot the light @over ai nd the moving of the paper roll, nre elt'ected by means ot' i driving spindle, but also the passage o if Se the peper roll thronghhe developing, lining and washing hath.

being pi i ted at Z and having its end opposite inoinlier e connected to a rod 7' through the niediuni of a pivot rf. The rod is co1ineetetl to an arm 1l2 having` one end attached` to a hinged Cover o which Cover rests on a photographie plate it and prevents light lroni gaining access toit except: when the cover is liftedl y illustrates the paper or sensitized .ele- Inent which is run from the roll o: end under the sensitized element g is a press plate m which is desi gned to press the sensitized inaterial into Contact with the photographic plete-Ft. The rod r has an aperture r3 1n it for the reception of the lower end of e rod g which rod o is attached to the press plate and intermediate the length of the rod g is a shoulder q which is designed as a beuring i'oi.' :t against an angular end ot the rod 1', the said angular end containing; theaperture r3.

The apparatus hss a. easing A `and the said casino; contains a receptacle t' designed to conta" developer, a receptacle i?, designedy provided with guiding e means tor the sensitized material sneh guiding means being .in the form of rollers s, 1)8 and e at the top of the receptacles and rollers It near the liottoins ol the receptacles, so that. the sensitized material being run in engagement with the said rollers is guided through the baths or liquids in the said receptacles. The receptacle is also provided with guiding-roll ers l, (l the paper s from the roll 2 which is for a purpose to he presently explained.

The arrangement works as follows: After the end of the roll of hroniid of silver, peper u, has been drawn over the' transport rolls ol the liquid receptacle, this strip is fastened between the two rollers and 0. By turning the crank and thc india rubber roller c are turnedby means ot the cog-wlieels e and f. By this ineens, the stri is drawn through the an rangement, until the hroinid of silver peper y is brought under the hotographio plate'h.. Although the hand oran dis alwaystiirning', the bron'lid of sllrerstrip reinainsfstill for n. shortI time, until the interval, a' of the oog-` Wheel e has passed the oog-Wheel f, and the teeth of the ti 7o Wheels catch into each other again. During this interval, the arm .c

sirnw f2 which s urine' also beers l :n j c and D for the purpose of guiding d, the wooden roller b which is iitted to the cog-Wheel c, presses on the lever Z, so that by the turning of 'the latter the hromid of silver' paper pressed against the photographic plate 7L through Wooden plate m, and at the same time the cover o et the frame p is raised, whereby the lighting ort' the paper takes place. The rods g and fr, which are connected respectively with the plate mand the cover 0 and are necessary for the pressing and lighting of the paper, are so arranged, that the rods only litt up the cover o, when oy means of the rod g the Wooden plate m has pressed the paper against .the plate 7L', so that the lighting of the paper may not take place-too soon. When the pressure of the arm is released from the lever Z, the latter goes hack into its place, and with it also the rods Qiand r. ils soon as the copying is inishcd, the cog-wl1eels e and catch into each other again, and the hromid of silver strip is pushed on farther the length of apicture, a'. c., until the interval on the cog-vvheel e comes again to the cog-Wheel Now the' paper ivhieh has heen pushed forward is *again exposed to the light, as already described, and so on. The copied strips are new tirst all brought from the roller s into the receptacle Az', containing developer, and passed over the roller a and the hot-tom ot' tank, up to the roller o, which positioned overthe partitionv between the receptacles or con'ipartments for the developing and fixing solutions. The strip is run overt-he other rollersI shown in the drawing, and is then, applied tothe tceding mechanism cons1st-` mg in part et' the rollers Z) and c, heretofore described. Through this arrangement of the rollers, the strip to he developed is drawn through the receptacle, and thereby hassutiicient time to develop. The developed strip is then in the same Way drawn through the fixing bath into receptacle w, and then through the Water oath m, so Athat it emerges linished from the ariange'inentl -through the rollers o and ,0. lf suthcient pictures have been made, and the roller fz has not yet been completely unwound, cover y is opened, the printed. istrips are to he cut oft from those still unexposed, and the former areto he joined 'to the ordinary strip e', made of chea) paper, so that this remains in the liqui receptacles While the apparatus is not in use, and there is a saving of the hrornid of silver paper. i

Reference has heretofore been made 'to the means for moving the cover and plate successively, that is to say, movingithe plate so as to engage the sensitized inaterial'prior tothe time the cover is lifted to such an extent' as to admit light, and in carrying out that feature of the invention, the said plate has a-rod @attached to, it, and the cover has connection with the rod r-to which the lever Z ispivotally connected. The lower end of l the rod r hasan angular portion r through which the rod g extends, and the said rod Q also has a shoulder g to engage a spring gf, which spring is interposed between the shoulder g and the end r' of therod 1 As the lever is oscillated, therefore, movement is communicated to the rod o', which in turn, through the agency of the spring, communicates motion to the lrod g, thus causing the plate to hear against the sensi# tized material in order that it .may be pressed against the photographic plate '-L, prior 'to the admission of light, as stated. In practice, the pressing plate need not travel a great distance from the' photographic plate, as it is only necessary to relieve the pressure on the photographic plate"I in order to 4permit the sensitized material. to move, hence the cover would not be opened sutticiently to admit light prior to the time the traveling plate engaged the material on the photographic plate.
